The Complete Guide to QR Code Generation
What this tool does
The QR code generator encodes a link or text into a scannable code, entirely in your browser. QR codes are useful everywhere in presentations, posters, and handouts — sending your audience to a survey, a download, or your contact card beats reading out a long URL. Understanding error correction and file formats is what separates a code that scans instantly from one that frustrates.
How to use it
- Enter your contentLinks, text, or Wi-Fi details all work — shorter content means a sparser, easier-to-scan code.
- Watch the live previewThe preview updates on every keystroke, no generate button needed.
- Pick an error-correction levelM for everyday use; go Q or H if you plan to overlay a logo or print small.
- Choose a download size256–512px is plenty for screens; pick 1024px or SVG for print.
- Download PNG or SVGPNG works everywhere instantly; SVG stays sharp at any print size.

The generated codes are static: the content is encoded directly into the pattern with no shortening or redirect service in between, so they never expire — and there are no scan analytics. If you need scan statistics, use a redirect-based short link instead.
Tips for best results
- Short links scan betterLess content means sparser dots — easier to read from farther away and at smaller sizes.
- Never invert the colorsScanners expect dark dots on a light background; inverted codes fail on many phones.
- Print at 2cm or largerOn business cards start at 2×2cm; scale posters with viewing distance.
- Keep the quiet zoneThe white margin around the code is required for detection — never crop it.
- Raise correction before adding a logoSwitch to H before covering the center, then test that it still scans.
- Test before publishingScan with two or three different phones — not after the posters are printed.

FAQ
QR Code Generator FAQ
These answers explain what the tool does, what files it supports, and where the current limits are.
Is my link or text uploaded anywhere?
No. The QR code is generated entirely in your browser using a local encoding library. Nothing you type is sent to any server.
Should I download PNG or SVG?
PNG is a fixed-size image that works everywhere — documents, chat, slides. SVG is a vector file that stays perfectly sharp at any size, the better choice for print and large displays.
What does the error-correction level do?
QR codes store redundant data so they stay readable when partially covered or damaged. Higher levels (Q, H) survive more damage but pack denser dots; L and M stay simpler and easier to scan from far away. M is a good default.
Do the generated QR codes expire?
No. These are static QR codes — the content is encoded directly in the pattern with no shortening service in between, so they keep working forever.
What is the logo in the middle — can I remove it?
It is the Tosea otter mark on a white rounded tile that keeps clear of the position markers, so scanning is unaffected. With the logo on, error correction rises to level Q automatically to cover the hidden dots. Switch Center logo to Off for a plain code.
